Creating Filling Surfaces

You can fill the space between three or more elements (curves or surfaces) that must be contiguous in only one point.

This task shows you how to:

Before you begin: Open an existing 3D shape containing curves and surfaces.

Fill the Space between Surfaces

You can fill the space between multiple surfaces.

From the Creation section of the action bar, click Fill .
Define the Deformation direction.
Select the edge of the first surface.
Select the edge of an adjacent surface.
Select the edge of all other surfaces, still going from one surface to its direct neighbor.

Once you have selected the last edge contiguous to the first selected surface, the filling surfaces are created.
In the App Options panel, click Continuities to display the continuity tags at the geometry.
Right-click the displayed text to edit the continuities.

Note: The Tangent continuity is available only when filling a closed contour.
Use the handles at the center point to deform the generated surfaces according to the selected Deformation direction.
While deforming, set continuities are retained.

The center point is not displayed if only one filling surface is created or when four filling surfaces are generated.
Right-click the handle to open the context menu.
Click OK.

Notes:

Make sure you select contiguous surface edges, especially when filling the space between more than three surfaces. Do not select edges randomly.
If four edges have been selected, a mono-patch surface is created. However, if three, five or more edges (up to nine) have been selected, as many surfaces are created as selected edges.
A gap between two selected edges that exceeds the set tolerance (0.01 mm) is identified for correction purposes. A text is displayed indicating the gap value, and the fill cannot be performed. If the gap is smaller than 0.01 mm, the fill is automatically performed complying with the tolerance all around the selected edges.

You can fill the space between curves and surfaces.

Select a curve, two surfaces supporting a blend surface, and the blend itself.
Click Apply.
The intersections between the selected edges on the surfaces and the blend limits are automatically detected, and the filling surface is created accordingly.
Note: Only the Point continuity is available on the curve.

You can fill three or more open-sided contours when composed of surface boundaries only.

Select an open-sided contour, from surface edges for example.
Click Apply.
A temporary blend curve is created to close the contour when you , allowing the system to compute the filling surfaces.

You can fill the space between two intersecting curves or surfaces forming an open angle.

Select the surface edges.
Click Apply.
The system automatically creates temporary curves matching the selected edges to close the contour before filling it.
